A Sub-cell Based Channel Reservation Method for MEO Network

Abstract— Medium Earth Orbit (MEO) satellite networks must be capable of handle the handover problem of users between different spot-beam cells. In this paper, a Sub-cell based Handover Scheme (SHS) is proposed to decrease the resource reservation time reasonably in the Dynamic Doppler-Based Handover Prioritization (DDBHP) scheme. In this way, we decrease the new call blocking probability effectively while keeping very small of the forced termination probability for the handover user, which greatly increases the resource utility. Simulation results verify the correctness of the proposed approach.

Index Terms— MEO satellite networks; handover management; time-based reservation.
